From The Hindu, July 21, 1975: Second link-up a cliff-hanger
Dr. Vladimir Syromyatnikov, the head of the Soviet-American task force which designed and built the docking mechanism used to join the two spacecraft during their flight together through space, said the final link-up had taken place under 'extreme conditions'.
The pitching and tossing about of the two spacecraft between 12:33 and 12:40 GMT had been 'rather unexpected', he said. Space controllers watching the action on their television screens lived through seven emotion-filled minutes, he added.
He said the fact that all went well in the end was proof of the ability of the mechanism to withstand all the shocks to which it was subjected. 'We do not know the exact reasons for yesterday's incident and specialists from the two countries are at work analysing the causes,' Dr. Syromyatnikov said.
The Soviet expert said it would not have been 'tragic' if the mechanism had buckled during the docking operation because the astronauts would have then taken immediate steps to separate the two spacecraft ready for their return to earth.
The docking mechanisms were not directly attached to the space capsules used in the descent to earth, Dr. Syromyatnikov noted.

From Lituya Bay to Icy Bay, some of the worst tsunamis in US history
As per the official website of World Data, 75 tidal waves classified as tsunamis have rocked the American shoreline since 1737. Here's a look at some of the deadliest catastrophes, as compiled by Freight Waves: Worst tsunamis to hit the US (Representational Image) Lituya Bay, Alaska (July 10, 1958) A magnitude 7.7 earthquake struck the Fairweather Fault in southeastern Alaska on July 10, 1958. Five people died as a result: three on Khantaak Island at the mouth of Yakutat Bay and two by their boat sinking at Lituya Bay. This generated a gargantuan wave to the height of 1,720 feet, the world's largest recorded tsunami, as per the Western States Seismic Policy Council. Icy Bay, Alaska (Oct. 18, 2015) According to the National Park Service, nobody was close enough to the catastrophe for any physical harm or injury to follow, although the infrastructure took a major hit as a result. The same was scattered in smithereens across a beach used for landing bush planes. Landslides typically happen in conjunction with tsunamis, specifically around Alaska's parks.

Triggered by a landslide, the maximum inundation distance was 2,000 feet inland along the north shore of the bay. Lituya Bay (Jan. 1, 1853) What was then the Russian part of America, a large landslide on the south shore of the bay near Mudslide Creek triggered a tsunami with a wave height of about 394 feet, which flooded the coast of the bay up to 750 feet inland. Due to a lack of official records, geologists have had to rely on studies and evidence from the region to piece together the event. Shumagin Islands, Alaska (Aug. 6, 1788) Unfinished Russian accounts point out that the area between east central Kodiak Island and Sanak Island most likely ruptured due to two tsunami-producing earthquakes in the summer of 1788. This was followed by a second earthquake that inundated the Shumagin and Sanak islands. Surveys estimate the magnitude of the earthquake at 8.0. With contribution from Stuti Gupta

China's J-36 Becomes First Fighter Jet To Land Amid Sea Storm, Surpasses F-16 And Su-57M
China's J-36 stealth fighter jet landed on the Fujian carrier amid six-metre waves in the South China Sea, showcasing advanced military capabilities with its unique design The skies have a new contender, and it's not the F-16 Fighting Falcon or the Su-57M fifth-gen fighter. China's stealth fighter jet, the J-36, has stunned military observers with a feat rarely attempted, successfully landing on a warship amid towering six-metre-high waves in open sea. While American and Russian jets struggle in such extreme maritime conditions, China's J-36 has now set a new benchmark in naval aviation. The test, reportedly carried out earlier this year in the South China Sea, involved the J-36 touching down on the deck of the Fujian aircraft carrier during a high-sea storm. The maneuver, considered near-impossible by traditional fighter jet standards, has not only demonstrated China's evolving military capabilities but also posed a serious technological challenge to the established aviation powers of several countries. Engineered with a ginkgo leaf-style flying wing and powered by three WS-19 engines, the J-36 cuts a formidable figure in the sky. At 23 metres long and weighing in at 54 tonnes, the jet is larger and more heavily armed than China's previous J-20. Its payload reportedly includes long-range PL-15 missiles and supersonic munitions, expanding its strike capabilities well beyond visual range. But it's not just about firepower. The J-36's edge lies in its resilience, particularly at sea. Fighter jets are notoriously difficult to land on swaying aircraft carrier decks in calm weather, let alone in six-metre waves and storm-force winds. That's where the J-36 makes its mark. Direct Force Control (DFC) The aircraft's tailless design would normally add to the challenge, but China's engineers have equipped it with a sophisticated Direct Force Control (DFC) system. Drawing inspiration from robotics, DFC allows for microsecond adjustments to control surfaces, enabling the jet to execute ultra-precise landings even in unpredictable conditions. In the 2025 test, Western naval experts reportedly looked on as the J-36 performed a clean landing on the carrier 'Fujian', a feat few other militaries could replicate under similar circumstances. The J-36 is also paired with the 'Fujian' carrier's electromagnetic catapult system, allowing quick and high-energy launches. This combination enhances China's capacity to operate effectively in volatile maritime zones including the Indian Ocean, an area of strategic interest to multiple nations. Its Active Electronically Scanned Array (AESA) radar and integrated electronic warfare suite add further combat capability, giving it stealth, surveillance and jamming functions in a single package.
